@ScienceGamer004 But, in all fairness to emulators "like GameCube", another answer could be YES, the Pi3 running RetroPie DOES let you add many MANY emulators "like GameCube", but simply not GameCube, as it would be too slow for that. Insomuch as the GameCube is "like" the NES (both are home consoles, albeit vastly different generations), depending on your needs, the Pi3 is a great option.
